CHANGE OVER POINTS

Change Over Points (COPs) are prescribed for all federal airways and jet routes. COPs are

established for preventing loss of navigation signal or to prevent adjacent channel interference.

At a COP, the TACAN should be changed from the station behind to the station ahead. The

COP is not depicted on charts if it is located midway between the navigation facilities. When the

COP is not located at the midway point, aeronautical charts will depict the COP location and

give the mileage to the NAVAIDs. Compliance with COP procedures assures that aircraft

navigation equipment will be tuned to the NAVAID assuring maximum accuracy in defining the

route. Note that, in the absence of information to the contrary, this is the nearest NAVAID.

INTERSECTIONS

Navigation via jet routes often requires utilization of intersections as turnpoints. Refer to

Figure 3-2. Picture a clearance from VHP via J24 to BIGXX intersection, then J29 to ROD.
